Question
I2C between 2 stm
Hi.I want to communicate between two stm32 of different cores via I2C, lets say between F0 and F7.F0 would be slave and F7 master.The idea is when user button on F7 board is pressed ,the control will shift to F0..but i don't know how to give a slave address to my F0 or which register or Hal library to use for slave address..So how can i do that and how to make sure that address is not already in use.
